I am developing a chrome extension and I wanted to know if there is a way to get inline css in chrome extension development. I also wanted updated inline css if someone updated it ? Please help me if anyone have an answer. I have tried chrome.devtools.inspectedWindow and able to get current and updated css files but not inline css.

I'm making a Chrome Extension which changes the layout of a website. When my extension is activated and the website loads, you can briefly see the real website then it switches to my modified version loading in all the CSS and JS from the Chrome Extension. Though I've used other extensions that do something similar but have it displayed before anything actually shows the real website. One example is Shine for Reddit. When Reddit shows, it shows the extensions version of the website right at the start. How can I do this?
We would like to use the Show Preview link via the General tab to share a link to an unpublished page for review. Unfortunately, the page generated seems unable to resolve the bundled .css and javascript and generates 404s for those files.
Anyone know of a way for the preview pages to resolve the bundled css properly?
If your links are not resolving then you have incorrect or invalid syntax in your CSS.
Regarding turning off minimization and it working further confirms your syntax is not correct. The minimization engine fails when it finds incorrect syntax.
To check this turn on minimization and load a page. Download the CSS from the source and look at the last line. There will be an error in the CSS if it has failed to minimize.
I am a beginner with dom and now I am trying via a chrome extension to modify the a generic page html elements.
I've searched about it but didn't find anything concrete that could help me solve this.
Do i need to add something to the manifest.json file to be able to do this?
Thanks in advance!
I am looking for a sample project that would compile a chrome and firefox extension that would run some JavaScript code after a page is loaded.
I already wrote a Chrome extension that does this, but I am looking for something cross-browser, that would allow me to build the same extension for Chrome and Firefox.
If this would also allow me to publish the extensions it would be great.

Here you can get firefox extension by submitting chrome extension.
With the Crossrider's framework you can build a cross-browser extension using only one code base that will work on Chrome, Firefox and also Internet Explorer and Safari.
So, with only using javascript single code base and the Crossrider API you can easily build your first cross-browser extension in no time.

Can anyone suggest a browser plugin that will let me override a website whenever I am loading a particular website.
Example Scenario:
Whenever I load yahoo.com I want to change on how it renders the html and behave.
It needs to be able to manipulate the DOM. example, it can change the attribute of an <img height="" width="" />, example the width and height of the image.
Aside from changing attributes it also need to be able to inject new elements. example i can insert new <divs> or <p>.
I also need to be able to manipulate the head tag as I like to insert external CSS and JS for the overrides.
I primarily use Google Chrome and Mozilla Firefox.
Thank You.
Chrome has native support and Firefox via a plugin for user scripts (also called greasemonkey scripts). They are essentially javascript files that are installed like an extension. At the top you define the domains for your script to run on and you have access to modify the DOM. There are lots of examples at http://userscripts.org/ . Load a few in chrome and then take a look at the user.js file source to see how they work.
You could also do it via a Bookmarklet, however they are more of a hack compared to Greasemonkey scripts
It's called the content scripts in Chrome extension.
